Yea, I got a little more done. Got the vents cut out in the door but still got a little cleaning up to do on them. It took a few hours to cut them out with a disk but their done now. Between rain and darkness, I haven't got a lot accomplished.....
The door is not cut out,,, I just went a lap around it with the cut wheel so I wouldnt have to re measure. I have a few questions. #1- When running the chimney in the calculator, do I need to put the FB measurement at 100%, or where I have it now @ 130% to get the right volume? #2- does it matter how many stacks you have as long as you have the proper volume? For example, instead of a 38" tall 5" chimney,,,,, could you have 2- 3" stacks 38" tall?
